' UNITED STATES PATENT oFrioE. I isARNns'r "WrI AI DD, or NEW YORK, 1v. r nssrenon 'ro r'nn'ron r. ciu r'r, or

. State of New York, have invented certain new and useful Improvements in Beaters, of which the following is a specification,

reference being had to the accompanying drawings.

The invention relates to beating, mixing and aerating devices employing reversible {Stating or interlacing floats or beating a es.

The objectof my invention is to providea beater having operating gear wheels of such structure and adjustment as Wlll secure relatively great strength, reliable action,

simple construction facture': v

Withtheselprincipal features in view, my invention consists of the novel and practicable construction and combination of parts and low cost of manuas herein set forth and illustrated.

Referring to the drawings, Figure l is a vertical side view of a beater embodying my invention, the nearer drive wheel ofwhich is partlybroken away; and Fig. 2 is a cross section of same on the line 22 of Fig. 1,

a part of the bearing sleeve' of the dual drive wheels being broken away.

Referring now 1n detail to the drawings; 1

represents a supporting frame the upper part 2 of which constitutes the usual handle.

In this supporting frame I have also provided a bearing 3, float support recesses 1,

and a retaining groove 5 for receiving the.

v attaching strap .or. split ring 14. Mounted on this supporting frame lfare dual driving wheels 6, which preferably have integrally connected therewith the sleeve bearings 7, which bearings are steppedat 8 for the purpose of keeping the dual wheels-in accurate relation to each other, these sleeve bearings 7 being inserted in the bearing 3 of the sup porting frame. A rivet or bolt 9 for the purpose \of rigidly uniting the dual drive wheels 6' is inserted through said bearings or sleeves andfa'stened in any convenient Way.

- The dual driving wheels 6 are provided with cogs.10,i extending approximately half wayaround their circumference as-shown,

and are di'sposed with reference to each other 'sothat the cogs on thegsector of. one wheel will lie opposite the plain surface 11 of the opposite wheel. These cogs are preferably Specification of Letters Patent.

arranged on the bias rather than pointing to a commoncenter for the purpose of more accurate engagement with the cogs of the pinion 16 which as shown is so disposed that its cogs do not point to the center of said drive wheels. It is obvious that the cogs of pinion l6 mav be made upon a bias and the cogs of the drive wheelscentrallydisposed, thus permitting similar accurate en- 'beaters; and additionally this positive and reliable cog engagement makes accurate and expensive axial adjustment of the drive wheels unnecessary. v

Inserted in the'reces'ses 4 of the support 1 are the'ends 12v of the float support 13. A strap or split ring or link 14 is provided to' lie in the groove 5- and hold the ends 12. of

the float support 13, in rigid relation to the supporting frame 1.

On the float support float 15,1 have provided pinions 16 and 17, one of which is connected to each of the upright portions of the float or beater blades.

The cogs on the lower'part of the pinion 16 are adapted to intermesh with the pinion 17,

and the cogs of the upper part of the pinion 16 are disposed to intermesh-the cogs 10 of the dual driving wheels 6. The upper part of the pinion'l? is cut away for the purpose of ,escaping'engagement or interference with the cogs 10 of the drive wheels. These pinions, 16 and 17 aregre'versibly rotatably 100' mounted with reference. to the float support. Rigidly attached to the lower ends of the pinions 16 and 17, are floats or heater blades 15,- the other ends of which are reversibly frotatably mounted upon the lower POItlOIlS' of the float support. 7

Having now described my invention, the

operation of the same is as follows, namely:

The crank 18.is manually operated in a continuous eirculardirectifibarrying wlth it \the dual driving wheels 6, the cogs 10 of- 1.3,at the head of i each wheel alternately engaging with the upper portion of the pinion 16 at opposite sides thereof. These cogs 10 of the driving wheels first engage one side of pinion 16, and then engage While I have described and shown an egg beater, it will be readily seen that'this device may be used for beating, mixing and aerating purposes generally. I have described my preferable method of practising my invention but do not wish to be limited to the description given and illustrated.

\V hat I claim as new, and what I desire to cover by these Letters Patent, is setforth in the appended claims.

1. In a heater, a supporting frame, dual driving wheels mounted on saiiLframe, each of said driving wheels having cogs on approximately one-half of its engaging surface and a plain elevated surface on the other approximate half thereof, said cogs on each driving wheel being disposed opposite to the plain surface of the other 'drive wheel, a pinion eccentrically disposed to and adapted to engage with the cogs of said driving wheels, and a second pinion intermeshmg with said pinion but disposed out of engagement with the said-dr1ving wheels,

.beater blades or members attached to said pinions, and means for supporting said heating members. 2. In a beater,- a driving wheel having cogs extending around approximately onehalf thereof anda plain surface extending around the balance thereof, said plain surface being elevated or thickened.

3. In a beater,

cogs approximately one-half of their rim dual drive wheels having ion adapted to engage pinion but so constructed that it will not ing disposed opposite each other so that the cogs on one wheel will be opposite the plain surface of the other wheel; a pinion eccenti'ically disposed to ternately engaged with the cogs of each of said driving wheels,

with the first named engage the cogs of said drive wheels, said pinions being mounted in a plane Within said driving wheels.

.4. In a heater, dual drive wheels, approximately one-half of the rim portion of each of said drive wheels bearing cogs, and the hahinee thereof having plain surfaces, said wheels being so disposed to each other that thecog surface of one wheel will lie oppo site to the plain surface of the other wheel,"

a pinion eccentrically disposed toa-nd adapted to engage with the of the drive wheels and a second pinion adapted to engage with the-first said pinion, said second pinion being so constructed as not to engage with the said drive wheels, and said pinions beingso disposed as to lie in a plane between said drive wheels.

5. In a heater, a drive wheel having cogs,

a pinion adapted tofengage with said cogs, a seeond pinionadapted to lntermesh with said first named pinion, but so constructed an intermeshing pinand adapted to be 'al- I as to escape engagement with the cogs of thef drive wheel, said pinions being so disposed as to lie in thesame plane which is a planesubstantially parallel with the plane of the cog surface of the driving wheel.

(i. In a beater, a driving wheel having cogsextending around approximately onehalt thereof and a plainsurface extending 1 around the balance thereof, said plainsurportion and plain surfacesfor the'bala'nce of said rim portion thereof, said wheels beface' being elevated or gral sleeve extending from said driving wheel said sleeve-being provided with an irregular end, surface adapted to engage a corresponding sleeve.
